convert_type(self, value, schema_type, **kwargs)[source]

Takes a value from Oracle db, and converts it to a value that's safe for JSON/Google Cloud Storage/BigQuery.

  • Datetimes are converted to UTC seconds.

  • Decimals are converted to floats.

  • Dates are converted to ISO formatted string if given schema_type is DATE, or UTC seconds otherwise.

  • Binary type fields are converted to integer if given schema_type is INTEGER, or encoded with base64 otherwise. Imported BYTES data must be base64-encoded according to BigQuery documentation:

  • value -- Oracle db column value

  • schema_type -- BigQuery data type
